6 Claims.

This invention relates to calendars and more particularly to calendars for use on desks.

An object of the present invention is to improve such calendars generally and particularly with respect to providing an improved binder post construction for the paper sheets which will be simple, efficient in use, and durable. Another object of the invention is to provide a desk calendar in which information of a temporary nature 0 may be recorded, yet which will serve also as a permanent record for happenings of importance, the elements thereof being so arranged that the temporary memoranda can readily be removed when no longer useful, Without affecting the permarient record. A further object of the invention is to provide a desk calendar in which the legs and binder posts are readily detached from the base so that the calendar as a whole can be placed in a compact container for shipment.

Other objects and advantages, as well as the novel details of construction of this invention, will become apparent after a consideration of the description hereinbelow set forth, taken in connection with the accompanying drawing and after a perusal of the appended claims.

A particular embodiment of our improved calendar is illustrated in the accompanying drawing, in which similar reference characters identify similar parts in the several views and in which Fig. l is a top view of the calendar; Fig. 2 is a section taken along the line 2--2 of Fig. 1; Fig. 3 is a section taken along the line 3 3 of Fig. 1; Fig. 4 is an enlarged detailed View of one of the binder posts, partly in section, and Fig. 5 is an enlarged detailed sectional view of one of the legs of the calendar.

Referring more particularly, to the drawing, the reference character I5 designates the base or stand of the calendar which may be formed of a piece of stamped metal, having suiiicient rigidity for the purposes intended. Any suitable metal may be used, such as steel, brass, etc. The metal may also be enameled, nickel plated, chrome plated or made of rust-proof steel. In any event, it is preferable that the surface shall be such as to be resistant against rust and shall be pleasing in appearance. Downwardly extending flanges may also be provided at the side end portions and at the rear end portion of the base to increase the rigidity of the same, to provide smooth edges and to give an impression of greater thickness than the thickness of the sheet metal of which the base is constituted. As shown more clearly in Fig. 3 of the drawing, the base is provided adjacently to the flange on its rear edge portion with a pair of legs EI which support the base in tilted position. The front edge portion of the base which rests on the table or desk is suitably formed into a trough I2 for the reception of pencils. A pile of superimposed sheets of paper are supported on the top side of the base and held in position thereon by the binder posts which are designated generally by the reference characters I3. The base I0 has a width which is slightly greater than twice the width of the sheets in the pile so that the paper sheets may be turned over the binder posts I3 as they are used to form two piles on such base, as is clearly shown in Fig. 1.

The pile of superimposed sheets is composed of a plurality of two different kinds of sheets I4 and I5, which are arranged alternately in the pile. The sheets I4 are made from paper stock which has relatively great strength and does not tear easily, while the sheets I5 are made from paper which is substantially weaker than that of which the sheets I4 are constituted. The sheets I4 are each provided with printed matter on both sides, the printed matter on each side of the sheet designating a different day'of the year. The printed matter on each of the sheets I4 may be so arranged that when the sheet is positioned on the right hand side of the calendar, as viewed in Fig. 1, the date designated is chronologically one day prior to the date designated on the opposite side of the sheet, so that by turning the sheet over the binding posts to the left hand side of the calendar, the diary page for the following day is presented. The sheets I4 may also have printed matter on each side, dividing the day into suitable time periods, such printed matter preferably extending lengthwise of the sheet adjacent to the left hand edge as viewed in Fig. 1. The sheets I5 are blank but may bear headings indicating that they are intended forV temporary memoranda. By reason of the above described arrangement of the sheets, there is always a dated sheet I4 and a sheet I5 on top of the piles. During the day those events which the user desires to keep for his permanent record are noted on the sheet I4, while any data of a temporary nature is noted on the sheet I5. By turning the uppermost sheet on the right hand pile of the calendar over the binding posts, the dated sheet I4 of the following `day and a vblank page I5 is presented. If a sheet I5 is on the left hand pile at the end of the day, the user may tear such sheet from the calendar, inasmuch as both of its sides have been covered with information of a temporary nature which is no longer useful. Thus, at the end of the year, the pile on the left hand side of the calendar will consist only of the dated sheets I4 which may then be removed from the base and led away as a permanent record. As the paper constituting the sheets l5 is relatively weak and the binding posts I3 are strong and solid by reason of their construction, as will be hereinafter explained, it will be seen that the sheets I5 can be readily torn from the calendar with facility. The sheets I4, however, being made of paper which is substantially stronger than that of the sheets I5, cannot be torn so readily from the calendar. The differences in strength of the sheets I4 and I5 is preferably such that the user cannot unknowingly tear a sheet I4 from the calendar by mistake.

The binder posts I3 are positioned near each other on the rear portion of the base so that they will not interfere with the userwhen he is writing on the sheets I4 and I5; this position of the posts also enabling the sheets I4 and I5 to be readily lifted from the front of the right hand pile and turned. Each of the binder posts I3 comprises a straight tubular female section I6, which is disposed vertically with relation to the top surface of the base I0. As is shown more clearly in Fig. 4, the lower end portion of the female section I6 extends through a perforation stamped out of the base I0 and is provided with an external screw thread I'I which is in threaded engagement with a female thread provided on the inner surface of the downwardly extending flange I8 stamped out of the sheet metal of which the base is constituted. The lower end portion of the female section I6 is securely held in position in the flange I8 by means ofthe nut' I9 which is screwed on the thread I'I and abuts against the lower edge of the flange I8. The height of the female section I6 above the base I0 is approximately equal to the thickness of the pile of superimposed sheets I4 and I5 so that the female sections of such binder posts ma'y serve as guides for placing the pile of sheets in position on the calendar. By loosening the nut I9 and screwing or unscrewing the female sec` tion in the threaded flange I8, it will be seen that the height of the female section may be varied to accommodate piles of sheets having different thicknesses. Preferably, however, the unthreaded portion of the female section is made of a length to accommodate a pile of sheets of a standard thickness. Y

The male sections of the binder posts each comprise a portion 20 which is disposed vertically with relation to the top surface of the base I0, a substantially horizontal portion 2| a vertically disposed portion 22 and a vertically disposed portion 25 which is of smaller cross-sectional area than the portions 20, 2I and 22. The lower end of the portion 20 extends through a perforation in the base I0 and is provided with an external screw thread 23 adapted to receive the nut 24 which is screwed tightly up against the under surface of the base I0 to securely hold the male section in position on the base. The reduced portion 25 is entirely contained within the upper end portions of the female section I6, the upper end of the latter abutting against the shoulder formed by the portions 22 and 25. The diameter of the reduced portion 25 is such that it may be readily inserted into or removed from the female section I 6, yet fits suilciently snug within the latter so that transverse movement between such parts is prevented. The length of the reduced portion 25 is approximately one-half the length of that portion of the female section I6 which rises vertically from the base Il) so that a solid strong connection is formed between the male and female sections of the binder posts. It will be seen that the above described arrangement of the parts provides a simple, strong construction, which in effect forms a permanent part of the base, yet which can be readily disassembled to insert or remove the calendar sheets. The latter act is accomplished by unscrewing the screw 24 from the thread 23 on the lower end of the portion 20 of the male member and moving the male section upwardly from the base, so that the portions 20 and 25 thereof are slidably withdrawn from the perforation on the base and the female section, respectively. The male and female sections may be made of any suitable metallic material such as steel, brass, etc. While we have shown the horizontally disposed portion 2I of the male member as straight, it will be understood that it may be arcuately shaped or formed in any other manner.

The legs II of the base I0 are each secured to the latter by means of a screw 29 which extends through the opening in a downwardly extending or countersunk flange 21 stamped out of the base and is in threaded engagement with a female thread provided on the wall of an axially L disposed recess in the upper end portion of the leg. The countersunk portion of the base is so formed that the top edge of the screw 28 is flush with the upper surface of the base I0. The upper end of the leg is provided with an enlarged recess 26 which communicates with the threaded recess and is adapted to receive the flange 21, thereby enabling the upper annular end of the leg to seat tightly against the under side of the base. 2S is approximately the same as the diameter of the flange 2 at the under surface of the base so that a snug t is presented thereby preventing the leg II from shifting from its intended position on the under side of the base. This arrangement is also advantageous in assembling the legs on the base because once a screw 28 is engaged with the female thread in a leg it is only necessary to turn the leg without holding the screw as the frictional contact between the side of the screw head and upper side of the flange 2 prevents the screw from rotating while the leg is being screwed into position. Thus the legs may be assembled on the base and secured tightly in position against the under side of the base Without the aid of a tool.

While we have illustrated and described a preferred embodiment of the invention, it will be readily understood that various changes in the form, construction and arrangement of the various parts of the invention may be resorted to without departing from the scope of the invention, hence we do not wish to limit ourselves strictly to the structure herein setforth.
